NDT Jobs & Salaries in Charleston, SC
The NDT job market in Charleston is shaped directly by its industrial base — Commercial aerospace (Boeing 787), Naval/Coast Guard ops, Container port. Major employers and asset owners in the area include Boeing South Carolina (787 Final Assembly), Joint Base Charleston, Nucor Steel Berkeley (regional), all of which run continuous inspection programs and rotate inspection contractors against multi-year MSAs. Code authorities most often cited in local procurement specifications are FAA Part 21 / 145, AS9100, Nadcap, so any inspector hunting work in Charleston should expect those references in interviews and pre-qualification packages. Wages track close to the national median for inspectors, with overtime making up the variable component. A recurring local theme: "Boeing 787 fuselage barrels are 100% PAUT-inspected before mate — losing one Level III qualification mid-shift can cascade into 48 hours of downstream paint-bay rework." Beyond the top-of-mind names, the deeper bench in Charleston includes Bosch Charleston — these are the employers that pre-qualification managers screen most often when filling rotational openings. BLS-anchored Level II wages in Charleston run around $76,000/yr; Level III with API endorsements layers on to roughly $118,000/yr — the gap between the two is the single biggest reason local inspectors pursue Level III. Jurisdictional layer matters here: AS9100 (Boeing) and Nadcap NDT apply on top of the federal/national codes, and missing the local-authority reference on a procedure submission is a common rejection reason for first-time-into-Charleston contractors. One angle that differentiates Charleston from peer markets: Boeing Charleston is one of two 787 final assembly lines globally. Turnaround calendar: Spring/Fall TARs — the inspection workforce flexes hard against this rhythm and overtime stacks during those windows.
